“To waste, to destroy our natural resources, to skin and exhaust the land instead of using it so as to increase its usefulness, will result in undermining in the days of our children the very prosperity which we ought by right to hand down to them amplified and developed.”

“Here is your country. Cherish these natural wonders, cherish the natural resources, cherish the history and romance as a sacred heritage, for your children and your children's children. Do not let selfish men or greedy interests skin your country of its beauty, its riches or its romance.”

“The nation behaves well if it treats its natural resources as assets which it must turn over to the next generation increased, and not impaired, in value.”

“Our duty to the whole, including the unborn generations, bids us to restrain an unprincipled present-day minority from wasting the heritage of these unborn generations. The movement for the conservation of wildlife and the larger movement for the conservation of all our natural resources are essentially democratic in spirit, purpose, and method.”

“There is a delight in the hardy life of the open.There are no words that can tell the hidden spirit of the wilderness, that can reveal its mystery, its melancholy and its charm.The nation behaves well if it treats the natural resources as assets which it must turn over to the next generation increased; and not impaired in value.Conservation means development as much as it does protection.”

“We should not forget that it will be just as important to our descendants to be prosperous in their time as it is to us to be prosperous in our time.”

“Our aim is not to do away with corporations; on the contrary, these big aggregations are an inevitable development of modern industrialism, and the effort to destroy them would be futile unless accomplished in ways that would work the utmost mischief to the entire body politic. We can do nothing of good in the way of regulating and supervising these corporations until we fix clearly in our minds that we are not attacking the corporations, but endeavoring to do away with any evil in them. We are not hostile to them; we are merely determined that they shall be so handled as to subserve the public good. We draw the line against misconduct, not against wealth.”
